Tesla desires to use the 48-volt electrical structure it debuted within the Cybertruck to autos from different manufacturers.
In a latest weblog put up, the automaker defined that it’ll implement what it calls the Low Voltage Connector Customary (LVCS), constructing off the 48-volt Cybertruck structure, in all of its autos to assist simplify {hardware}. And, very similar to the North American Charging Customary (NACS) DC fast-charging connector, it is pitching LVCS to different automakers.
The LVCS narrows the variety of electrical connector sorts wanted in new automobiles down to 6, in line with Tesla, whereas assembly the necessities for 48-volt operation like elevated spacing between contacts. That is important to stop arcing and shorting as soon as the present is stepped up from the present auto-industry commonplace of 12 volts to 48 volts.

Tesla believes a 48-volt electrical structure is the “optimum long-term alternative,” noting that it requires one quarter of the present to ship the identical quantity of energy, and claiming that it’ll assist guarantee dependable operation of autonomous-driving programs.
After Tesla rallied to drop 12-volt lead-acid accent batteries from its EVs, it made the complete leap to 48-volt with the Cybertruck. Subsequent-generation Ford EVs would possibly do the identical. However these aren’t the primary automotive functions of 48-volt tech.
Gentle hybrids have used 48-volt electrical architectures for over a decade. Satirically, these programs all had DC step-down and carried over a 12-volt system for equipment—whereas suppliers extolled the virtues of going 48-volt for every part. Automakers did not chunk, although, primarily because of the excessive price of upgrading all electronics without delay.

Now, with autonomous autos, standardized parts, and streamlined connectors in thoughts, Tesla’s framing of its 48-volt {hardware} as a brand new {industry} commonplace may permit prices to be shared.
It is labored for Tesla earlier than. In 2022 it made a robust enchantment to the {industry} to make use of its NACS connector. By the tip of 2023 each main model within the North American market had dedicated to migrating to it.
